Method for thickness regulation during a hot-rolling process

Abstract

A flooring system comprises a preformed composite panel having a first sheet ( 2 ), a second sheet ( 3 ) and a core of insulating material between the first and second sheets ( 2, 3 ). In one case the sheet ( 2 ) is a generally flat top sheet and the sheet ( 3 ) is a profiled bottom sheet. A floor such as a wood effect floor ( 5 ) is laid over the flat top sheet ( 2 ). An acoustic barrier layer 6 is located between the floor ( 5 ) and the sheet ( 2 ). The profiling of the sheet ( 3 ) defines channels ( 7 ) for location of service ducts/conduits ( 11 ). A planar facing ( 8 ) is applied over the profiled sheet, bridging the channels ( 7 ).

1 . A method for automatic gage control during hot rolling with at least one rolling stand, where factors that are considered include the present mean position of the adjustment cylinders of the rolling stand and their total rolling force, wherein at least one additional position measurement is carried out by detecting position signals in the immediate vicinity of the roll gap of the rolling stands and that the position signals are used for calculating the strip gage. 
     
     
         2 . A method in accordance with  claim 1 , wherein the position signals are detected between the work rolls and/or the backup rolls and/or the work roll chocks and/or the backup roll chocks. 
     
     
         3 . A method in accordance with  claim 1 , wherein the position signals are used for automatic position control. 
     
     
         4 . A method in accordance with  claim 1 , wherein the position signals are used for automatic swivel control.
